I use a little oneliner with tofi (rofi/wofi would also work) to select the current output and avoid pavucontrol. It’s mapped to a sway binding but would probably work in any wm/de:
<span style="color:#323232;">pactl set-default-sink $(pactl list short sinks |awk '{print $2}' |tofi $tofi_args)
</span>
I’m using pipewire so the functionality of pactl is actually provided through pipewire-pulse I think
